Voters in an upscale district of Karachi turned out in low numbers on Sunday for a repeat of the parliamentary election there, a day after a prominent official in a major political party was gunned down in the area, officials said.

The district was a focus for accusations of election fraud during national voting on May 11, and voting there was suspended early that day after reports of violent intimidation. In particular, Pakistan Tehreek-e-Insaf â€” the party led by the former cricket star Imran Khan, which has made inroads among affluent Karachi voters â€” blamed the dominant party in the city, the Muttahida Qaumi Movement, of trying to prevent his supporters from reaching the polls.
